Battery Safety

Lithium-ion (Li-Ion) batteries have become extremely common. They are found in virtually every rechargeable/electronic device, from personal devices (Bluetooth headphones, vape pens, cell phones, computers) to transportation (e-scooters/ebikes, electric vehicles, airplanes) to stationary home/commercial Battery Energy Storage Systems (BESS, e.g., Tesla Energy Wall or Megapack), and many other applications. If these batteries suffer a catastrophic failure, they can create extreme heat, result in a fire or explosion, and produce toxic gases.
